Though Harker had told them that the curse was still present and his hunger for flesh was strong as ever, it didn't feel right for anyone to make him sleep in the confinement room again. And so they all headed for a hotel with him wearing a scented face mask to hopefully drown out the human scent.
It didn't do much, but it's better than nothing. Harker already knew himself well enough to know that unless someone gets really, REALLY close, he won't just pounce on people like he did before.
He really felt sorry for that bodyguard who lost his arm. But the fella happened to be a very chipper one, as all he said was:
"Haha, it's no problem! I still have another one, and I happened to be left-handed so at least I didn't lose my dominant hand!"
Roland assured him as well. "We will have a prosthetic arm be done for him in just a few days. Don't worry about it."
